This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This University of New Hampshire team has recently developed a fully automated version of a popular and familiar shock analysis code, based on the solution of the Rankine-Hugoniot relations, creating a tool that is accessible via the internet. The code utilizes real-time data from the Advanced Composition Explorer (ACE) spacecraft to provide solar wind shock solutions within 10 minutes of a shock's passage by the ACE spacecraft, located at the Sun-Earth Lagrange point (L1). These solutions provide approximately one hour advance notice before such shocks impact the Earth's magnetopause. In this effort, the Principal Investigator (PI) and his team will upgrade the performance and utility of the web page and associated tools, while adding features not currently available. The planned enhancements will provide more reliable determination of shocks and their parameters, and predict the likely characteristics of approaching ICME sheath regions, which are known to be space weather drivers. The team will perform statistical studies of past shocks in order to improve existing codes and allow them to provide this new information. The PI notes that automated space weather analyses running in the public domain have proved useful during the recent solar maximum. Such analyses are expected to play an increasing role in society's efforts to protect itself from geomagnetic storm effects originating with solar transient events. The PI's automated code can provide advance warning of approaching shocks so that actions can be taken to protect biological, industrial, and technological assets that may be adversely affected. The PI's team will also recruit and employ undergraduate physics majors to work in this effort. The project will provide these students with experience in data reduction and programming techniques, training in shock physics and space science, and practice in writing scientific papers. The PI has a history of mentoring successful undergraduates who have written significant research papers and presented them at international meetings.

该奖项是根据2009年的《美国复苏与再投资法》（美国法律111-5）资助的。这家新罕布什尔大学的团队最近开发了一种完全自动化的版本的流行且熟悉的震惊分析法，该版本基于兰金的解决方案-Hugoniot关系，创建可以通过Internet访问的工具。 该代码利用高级构图资源管理器（ACE）航天器中的实时数据在位于Sun-Earth Lagrange Point（L1）的ACE航天器的冲击通道后的10分钟内提供太阳电击解决方案。 这些解决方案在这种冲击会影响地球磁性的情况下提供了大约一个小时的提前通知。 在这项工作中，首席调查员（PI）和他的团队将升级网页和相关工具的性能和实用性，同时添加当前尚不可用的功能。 计划的增强功能将为冲击及其参数提供更可靠的确定，并预测接近ICME护套区域的可能特征，该区域已知是太空天气驱动因素。该团队将对过去的冲击进行统计研究，以改善现有代码并允许他们提供此新信息。 PI指出，在最近的太阳能最大值中，在公共领域进行的自动太空天气分析已被证明很有用。 预计此类分析将在社会保护自己免受太阳瞬态事件的地磁影响的努力中发挥越来越多的作用。 PI的自动代码可以提前警告接近冲击，以便可以采取行动来保护可能受到不利影响的生物，工业和技术资产。 PI的团队还将招募并聘请本科物理专业的专业，从事这一努力。 该项目将为这些学生提供减少数据和编程技术的经验，冲击物理和太空科学的培训以及撰写科学论文的实践。 PI有指导成功的本科生的历史，这些大学撰写了重要的研究论文并在国际会议上介绍了这些论文。
